Now that people have the Treo Pro there should be some experience with 3rd party apps and the 320x320 square screen. I am on the fence about getting one because I use a few 3rd party apps extensively. For example, being able to run Audible Player, iNav's GPS (iGuidance) and Intelligolf (for the GPS distances) is very important to me.

So my question is what apps do you use that you know are supported by the Treo Pro without having to use something like realvga?
